Dear all,

I connected two cpus 412-5H and ET200S through Scalance X208. I did the hardware configuration in step 7. How I know (test) if there is connection between them or not? Thank you

hi Alsalami,

HW-connection is one thing. But how do you want to communicate? 

Do you want to make an S7-connection? Or an I-Device configuration?

Which blocks do you use to communicate?

Have a look to this manual. There you can see what is possible with this combiniation, page 101:

CPU-CPU Communication with SIMATIC Controllers

hope this helps,

 Thank you for your reply. I want to test my hardware as a CPUs if they communicate with each other or not. Im new to it. so not sure how to do it. 

Also I have 412-5H cpu and the document you suggest said:

In the document, the following components are not discussed:

• SIMATIC Controller LOGO!

• H-CPUs, T-CPUs

• Components to be phased out

hi Alsalami,

sorry, I didn´t mentioned it is an H-system.

you will find Infos about communication in an S7-400h-system in the manual of it, chapter 14:

SIMATIC Fault-tolerant systems S7-400H

As I see, the following communication is possible:

-S7-communication

-PN-communication

-Open communication

What do you use? Or what do you want ot use?

hope this helps,

 I have two 412-5H cpus in redundency mode. they communicate with each other by obtic cable. they connected to scalance x208 by ethernet cable then from the x208 I connected the ET200S using ethernet. Now the scalance red led is on and I dont know how to test if the connection between 412 cpu and ET200S cpu is there or not. sorry for the head ache and thank you for your help.

Hello,

Have you checked the diagnostic buffer of S7400H plc?

Have you assigned same online and offline device name to ET200S?

Use CPU clock to activate one of the DO module  output of ET200S IM for checking.

It should on/off even if you change from master to slave or vice versa.

 Hello 

Actually I have communication modules attached to the ET200S. that why I dont know how to test them.
